Armughan Al-Haq works with the Waterloo Institute for Sustainable Energy (WISE) at the University of Waterloo (UW) as the Manager of Program Development, Partnerships and Finance. He has completed his bachelor’s degree in Health Studies (BHS) from York University. Afterwards, he went to the University of Waterloo and graduated with a master’s degree in Business, Entrepreneurship & Technology (MBET) from the Conrad School of Entrepreneurship and Business followed by another master’s degree in applied science (MASc) from the Department of Civil Engineering. His research focus is in the area of renewable energy systems (geothermal, wind, solar, biomass), climate finance, net zero buildings, capital/financial markets, and health economics. He brings a unique interdisciplinary perspective with strong experience in the business/finance and energy sector. At WISE, Armughan is responsible for the successful execution of multiple R&D projects initiated by WISE in collaboration with different universities, research institutes, government agencies, and industry partners. He manages the strategic initiatives of WISE in enhancing its project portfolio, investment capital, and I.P capacity in the renewable energy sector leading to research commercialization, prototype development, and deployment of pilot projects on a nationwide scale.
Two novel four-blade H-darrieus vertical axis wind turbines (VAWTs) have been proposed for enhancing self-start capability and power production. The two different airfoil types for the turbines are assessed: a cambered S815 airfoil and a symmetric NACA0018 airfoil. For the first novel wind turbine configuration, the Non-Similar Airfoils 1 (NSA-1), two NACA0018 airfoils, and two S815 airfoils are opposite to each other. For the second novel configuration (NSA-2), each of the S815 airfoils is opposite to one NACA0018 airfoil. Using computational fluid dynamics (CFD) simulations, static and dynamic conditions are evaluated to establish self-starting ability and the power coefficient, respectively. Dynamic stall investigation of each blade of the turbines shows that NACA0018 under dynamic stall impacts the turbine’s performance and the onset of dynamic stall decreases the power coefficient of the turbine significantly. The results show that NSA-2 followed by NSA-1 has good potential to improve the self-starting ability (13.3%) compared to the turbine with symmetric airfoils called HT-NACA0018. In terms of self-starting ability, NSA-2 not only can perform in about 66.67% of 360

One significant obstacle to the adoption of geothermal heat pump (GHP) technology is the installation costs of geothermal heat exchangers (GHE). Cost reduction through optimization of system parameter offers the potential for increased applications. In the current work, five major parameters are considered: length, radius, well numbers, the flow discharge inside the pipe, and the pipe's external radius for optimization using a genetic algorithm (GA) for a residential building in hot climatic conditions. In addition, system optimization is critical in determining values of design parameters for assessing the impact different circulating fluids on the energy consumption of GHP. A ten-year simulation is undertaken to evaluate the capacity of various circulating fluids and their effects on energy consumption reduction. The simulation shows a significant decrease in energy consumption based on varying levels of Ethylene glycol, Methanol, Potassium acetate, Sodium chloride, Freezium™ compared to pure Water in the GHP. The COP of the GHP system is also calculated with different circulating fluids. In addition, the circulating fluid with the highest performance loss during ten years of operation is identified. Based on the results, Ethylene glycol is selected as the preferred solution for use in the GHP. In the present study, we have also established the optimum configuration of GHEs according to a reliable evolutionary algorithm for investigating the effect of various circulating fluids on the system's energy consumption.

Using fins on the inner and outer surfaces of pipes is one method to improve the heat transfer rate of ground heat exchangers (GHEs), thereby reducing the borehole depth and construction and operation costs. Results of 3D numerical studies of simple and finned U-tubes with outer and inner fins are evaluated for GHEs under similar physical conditions. Dynamic and static simulations show the effects of longitudinal fins on the thermal performance of borehole heat exchangers (BHEs) and heat transfer rate between circulating fluid and soil around pipes, while the dynamic tests include short timescale and frequency response tests. The results indicate that the maximum fluid temperature change is about 2.9% in the external finned pipe and 11.3% in the internal finned pipe compared to the finless pipe. The effects of the inlet velocity on temperature profiles, the patterns of the velocity and temperature contours due to the borehole curvature and the response times of the systems under various frequencies are also investigated in detail.
